We operate the pilot paper machine at UW-Stevens Point. This Fourdrinier machine has a 20-inch web, runs at speeds up to 200 fpm, and produces a sheet in basis weight from 15 to 400 gsm. Chemicals can be metered in at seven locations in the approach flow system; the pre-fan pump port is a co-mix port that can meter in two chemicals. The wet end includes a dandy roll, single-felted two-nip press and a smoothing press. The dry end features two independent dryer sections, a horizontal size press and calender stack. The stock preparation area features a hydropulper, two-stage cleaner system, slotted pressure screen and automated temperature control. In short, this machine is ready for your project needs.
